COMBINATION NUT-LOOK.

Specification of Letters Patent.

Patented Tune 22, 1909.

' positions which contain an elastic substance,

and has for its object to produce a simple, effective device of this character which may be readily a' plied to any class of bolts or threaded ro s now in" general use, without necessitating changes in the construction of the threads, or other arts of the bolt. The standard nut as pro uced by the manufacturer may readily be conformed to the shape reqluired to receive the gasket or composition col ar which is claimed to'be the attachment to the nut for breaking the vibration of the workings of the plate from between the face of the nut and the article to which the nut is ap lied by connection of the bolt.

ith these and other features in view the invention comprises the novel features of construction and combination of parts more fully hereinafter described.

In the accompanying drawings Figure 1 is a side view of-a bolt with the nut and collar or gasket attached, dotted lines representing the gasket'or collar and the inner cavity of the nut which receives the gasket with the nut relieved from the timber or plate showing the required extensions of the'gasket' that will form the compression between the nut and plate when drawn down solid to the late.

This collar or gasket is intended to brea the vibration between the nut and plate, thus preventing it from slipping or turning. Also the object of the gasket is to prevent the oil from leading in the threads to the face of the nut, thus preventinthe nut from being loosened by the application of the oil. Fig. 2 is a side and sectional view of the bolt, plate, and nut with the nut drawn solid to the plate for the purpose of showing the position of the gasket or composition collar in the cavity of the nut when in a working position. This inner cavity of the nut is threaded for the purpose of holding the gasket in a the bolt. Fig. 3 shows a side and sectional view of a bolt with the gasket or collar attached, and the nut detached. The sec tional view of the nut shows one method of making a nut of this kind with the inner cavity exposed, showing the form and manner of construction. Fig. 4 shows a side and top view of the nut the dotted lines re resenting a threaded ortion of the nut bot top and bottom, an the inner cavity of the nut which containsthe gasket. Fig. 5'shows a top and side view of the gasket as constructed for use, the dotted lines representing the impression of the'thread.

Similar letters refer to similar parts throughout the several views.

A. is the bolt, provided with threads, to which nut-B is attached.

E is the inner cavity of the nut B, which contains the gasket 0.

C. is the gasket or collar which is shown in each of the different views in different positions.

In attaining these ends, it "is to be understood that minor changes in the form, proortions,.and general assemblage of the arts e'rein set forth may be resorted to wit out Having thus described my invention, what I claim as new and desire to protect by Letters Patent is,

In a nut lock,'the combination of a metallic nut, provided with an annular threaded cavity, an elastic annular gasket to screw tightly intosaid cavity and project beyond said nut when in, both nut and gasket threaded to receive a threaded bolt, and said bolt, all substantially as set forth.
